ABSTRACT
Energy for heating and cooling, energy for transport, and electricity drive our economy and determine our well-being and that of our environment. Even in agriculture, which is by and large mechanised, energy cut would have dramatic consequences and affect our food supply. The treaty refrains from mentioning coal energy as the bad one, the climate killer. The motto of the conference was energy independence through renewable energy. The motto of the conference was energy independence through renewable energy. Before industrialisation started in the 19th century, the world relied almost exclusively on solar energy in its different forms. The meaning is that neither solar radiation nor wind flow is available continuously and the same holds for solar Photovoltaics (PV) and wind power that employ them. The Concentrating solar power (CSP) series’ growth in Spain was cut after the country discontinued all support for solar power, for CSP and for PV alike.
